Hi,

I have downloaded a patched version of the U-boot 1.1.4 for the AT91RM9200 EK board from an Atmel FTP site. I have also downloaded a cross compiler from Codesourcery. The name of this cross compiler is arm-none-linux-gnueabi-gcc. I use Linux Ubuntu and in the .basrc file I add the path (export) where the binaries of the cross tool chain are, after that I save it and I close the shell. In the Makefile of the u-boot I change the name of the cross compiler for the ARM architecture:

ifeq ($(ARCH),arm)
CROSS_COMPILE = arm-none-linux-gnueabi-

After that, I configure the board with 'make at91rm9200ek_config' and finally 'make all'. It compiles without any erro, only warnings and I obtain the file 'u-boot-at91rm9200ek.gz' (54,6 KB) after doing 'gzip -c u-boot.bin > u-boot-at91rm9200ek.gz'. Then I take this file and I download it to the Flash Memory:

tftp 20000000 u-boot-at91rm9200ek.gz
protect off 10010000 1001ffff
erase 10010000 1001ffff
cp.b 20000000 10010000 ffff
protect on 10010000 1001ffff

It doesn't occur any error when I'm copying the file to Flash Memory. When I restart the board in the EXT position of the BMS, a red LED switch on and appear the message:


Uboot>


boot 1.0 (Aug 8 2003 - 12:29:00)


Uncompressing image...

And nothing else happens. After that I follow the Flash memory recovery procedure and I download the 1.1.1 u-boot whose binary files are in the CD of the board. In this way I don't have to compile anything.

I don't know what I do wrong. If someone knows, please answer me.

Thanks in advance,

Javier

It is caused propably by a lack of pre-boot loader (bootstrap) which is based below u-boot section (on 0x10000000 to 0x10001fff). I've the same problem 3 weeks ago, try to search for boot.bin file on the cdrom included to ek board.
